The article examines ways of representing nuclear catastrophe in Kate Brown's Plutopia: Nuclear Families, Atomic Cities, and the Great Soviet and American Plutonium Disasters. In 1957 an explosion in the Mayak works - a plutonium production site - led to massive contamination of the surrounding areas. The event remained a closely kept secret till 1992, absent from the public sphere and cultural texts, despite the fact that the scale of contamination was as big as the Chernobyl explosion. One of the reasons for this was the difficulty of representing nuclear radiation. The author focuses on three contexts of this impossibility: in relation to the cognitive theory of the metaphor, the figure of the sick body as bearer of memory, and the invisibility of the nuclear landscape.

In the current study, promising glass composites based on vanadium pentoxide (V2O5)-doped zinc borate (ZnB) were investigated in terms of their nuclear-radiation-shielding dynamics. The mass and linear attenuation coefficient, half-value layer, mean free path, tenth-value layer, effective atomic number, exposure-buildup factor, and energy-absorption-buildup factor were deeply simulated by using MCNPX code, Phy-X PSD code, and WinXcom to study the validation of ZBV1, ZBV2, ZBV3, and ZBV4 based on (100−x)(0.6ZnO-0.4B2O3)(x)(V2O5) (x = 1, 2, 3, 4 mol%) samples against ionizing radiation. The results showed that attenuation competencies of the studied glasses slightly changed while increasing the V2O5 content from 1 mol% to 4 mol%. The domination of ZnO concentration in the composition compared to B2O3 makes ZnO substitution with V2O5 more dominant, leading to a decrease in density. Since density has a significant role in the attenuation of gamma rays, a negative effect was observed. It can be concluded that the aforementioned substitution can negatively affect the shielding competencies of studied glasses.
